Ocean Cleanup presents Floating Screens

Ocean Cleanup presents Floating Screens

According to Boyan Slat, the increased efficiency of the system, allows for the cleanup of half the Great Pacific Garbage Patch in just 5 years.

Dutch foundation The Ocean Cleanup announced it will start extracting plastic from the Great Pacific Garbage Patch with a new concept: Floating Screens. The new developed technology is based on floating ‘anchors’, instead of the initially planned fixed anchors.

Series of floating anchors (two black structures) are to keep the screen in place.

The cleanup system is already tested. Read More

California tests battery sites

California tests battery sites

One of many battery-system components that, it is hoped, will help California bolster its power grid.

Utilities have been studying batteries nationwide. But none have moved ahead with the gusto of those in Southern California.

After the giant gas leak in Oct. 2016, Californian engineers decided to turn to another technology, batteries. 

They freed up the utilities to start installing batteries – huge battery sites.

And, as a result: it’s the worlds first battery side test of this size.  Read More

Solar modules automated test-measurement system

Solar modules automated test-measurement system

The research team intends to lower the integral costs of PV-modules, by developing a worldwide unique AAA-class In-Line steady state solar simulator (ILSS) prototype for the PV-industry that is validated on criteria for test speed (5 modules/minute), test accuracy, heat development, maintenance and lamp replacement costs.

Why do we need an automated test-measurement system for Solar modules? PV-module manufacturers require automated inline testing equipment that provide accurate information about PV-module performance with industrial robustness and low testing cost per module. 

Several factors affect a cell’s conversion efficiency value, including its reflectance efficiency:

  • thermodynamic efficiency
  • charge carrier separation efficiency
  • and conduction efficiency values

Merits Heat Battery Tested

Merits heat battery

The thermal energy can be stored with a high density while limiting the energy losses to the ambient

Since May 2016, the Merits prototype of a compact rechargeable heat battery is tested. The test will take the whole summer. 

The battery is developed including high energy density thermochemical materials that can supply required heating, cooling and domestic hot water for a dwelling with up to 100% renewable energy sources (e.g. the sun) throughout the year. Read More

Test Prototype Ocean CleanUp

Test Prototype Ocean CleanUp

During his diving holliday in Greece, he found more plastic bags than fish. Now he is 21 and CEO of a high-profile company whose mission is to clean up the incredible amount of plastic floating around in the oceans.

This Prototype developed to CleanUp the Oceans, can be a real game changer.

Since today, the first prototype of the ocean cleanup installation is ready to test.

It’s an invention of Boyan Slat, with which he wants to clean up the plastic debris in the oceans.

Instead of an installation of one hundred kilometers in length, this scale model is a one hundred meters long prototype which is posted for the Dutch coast in the North Sea. Read More

Windturbine with 4 rotors

Vestas Windturbine with 4 rotors

In cooperation with the Technical University of Denmark, Vestas is installing a concept demonstrator to test the technical feasibility to operate and control a multi-rotor turbine.

A windturbine should generate more electricity. But how?

The Danish Vestas Wind Systems may have an answer.

The company is currently testing a windturbine with four rotors. Read More
